Description

Pressing wheel mechanism for rack

Technical Field

The utility model belongs to the technical field of the pile up neatly packing technique and specifically relates to a pinch roller mechanism for rack.

Background

In the cement manufacturing enterprise, the terminal can dispose the auto loader. The width-adjustable automatic car loader is characterized in that the width direction of the automatic car loader stretches out and draws back by converting circular motion into linear motion through a gear rack structure. The gear and the rack need to be tightly meshed so as to ensure the stability of the extending and retracting processes of the left side and the right side of the car loader. Because the space inside the automatic car loader is narrow, the hold-down mechanism of the gear and the rack on the market can not be used.

Therefore, it is required to design a pressing wheel mechanism for a rack bar that can be used in a narrow space to tightly engage a gear of an auto-loader with the rack bar.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a can be in the pinch roller mechanism who is used for the rack that uses in narrow space to make auto-loader's wheel and rack closely mesh.

In order to achieve the above object, the utility model relates to a pinch roller mechanism for rack, including support, adjusting bolt, gyro wheel, dabber, bearing, jump ring, axle sleeve, locking bolt, its characterized in that: the dabber is installed on the axis of gyro wheel, adopts bearing, axle sleeve and jump ring to be connected between dabber and the gyro wheel, adopts locking bolt to connect between the both ends of dabber and the support, has two through-holes and two screw holes on the support bottom plate, and the through-hole on the support bottom plate is passed to the uide pin on the main equipment bottom plate, and adjusting bolt is connected with the screw hole on the support bottom plate, and the top of gyro wheel contacts with the bottom of main equipment rack.

The bearing between be equipped with the axle sleeve, the bearing outside be equipped with the jump ring.

Compared with the prior art, the utility model, designed pressing wheel mechanism, support main equipment rack bottom through the gyro wheel, in automatic loading machine's narrow space, realize that wheel and rack closely mesh, the side stretches out and the even running of withdrawal process about guaranteeing the carloader.

Drawings

Fig. 1 is a structural diagram of the present invention.

Fig. 2 is a schematic view of the present invention.

Fig. 3 is a sectional view taken along line a-a of fig. 2 according to the present invention.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1, the utility model relates to a pinch roller mechanism for rack, dabber 4 is installed on gyro wheel 3's axis, adopts bearing 5, axle sleeve 7 and jump ring 6 to be connected between dabber 4 and the gyro wheel 3, is equipped with axle sleeve 7 between the bearing 5, and the bearing 5 outside is equipped with jump ring 6. Two ends of the mandrel 4 are connected with the bracket 1 by a locking bolt 8, a bottom plate of the bracket 1 is provided with two through holes and two threaded holes, and a guide pin 12 on a main equipment bottom plate 11 passes through the through hole on the bottom plate of the bracket 1 to play a role in guiding; adjusting bolt 2 is connected with the screw hole on the support 1 bottom plate, and adjusting bolt 2 adjusts the height of whole group mechanism apart from main equipment bottom plate 11, and the top of gyro wheel 3 and the bottom contact of main equipment rack 13.

Referring to fig. 2 and 3, the utility model discloses at the during operation, whole mechanism passes through-hole on the support 1 bottom plate and links to each other with welded uide pin 12 on the main equipment bottom plate 11, installs on main equipment bottom plate 11, and gyro wheel 3 and the contact of main equipment rack 13, main equipment rack 13 top and the closely mesh of main equipment gear 14.

The adjusting bolt 2 can change the space between the bottom plate of the bracket 1 and the bottom plate 11 of the main device, thereby realizing the tight press fit of the roller 3 and the rack 13 of the main device. When the main device rack 13 reciprocates, the roller 3 rotates therewith, and can be securely engaged with the main device gear 14 throughout the entire working stroke of the main device rack 13.

The utility model discloses a pressing wheel mechanism supports main equipment rack 13 bottom through gyro wheel 3, in the narrow space of automatic loading machine, realizes that wheel and rack closely mesh, guarantees the even running that the side stretches out and the withdrawal process about the carloader. The utility model has the advantages of simple structure, convenient adjustment and space saving.
